What can it Be? I have a Mitsubishi Big Screen TV and when we bought the new home theater system and hooked it up, it blinks blue back and forth for seconds at a time when we are watching DVD movies. The DVD is the home theater system. it is a DVD and home theater system in one. What can this be? THank you.
If I had to guess, I'd say that you need to check the video cable you're using to plug the DVD/Home theater system to the TV. Make sure it's a solid connection at both ends. If so, and the problem persists, try replacing the cable with a new one.
Start there, and post back with the results.
Thanks for the prompt reply. I don't know if my fiance did anything ,but we just saw a DVD movie and it didn't blink at all, so who knows, hopefully he did something and fixed the problem. Thank You very much.
